I Built an Anime Tracker That Works Offline (No Backend!)

I got tired of anime tracking apps that need constant internet, so I built my own over a weekend. It's a simple kanban board (React + Tailwind) that saves everything to localStorage first - works completely offline. You can optionally sync to your own Google Sheet for cloud backup, no backend server needed. Key thing: your data stays in YOUR browser. If you enable sync, it goes to YOUR spreadsheet, not mine.no tracking, no costs. Tech: React 18, Vite, localStorage, Google Apps Script (optional)
